Vacuum phenomenology of the chiral partner of the nucleon in a linear sigma model with vector mesons

Susanna Gallas, Francesco Giacosa, Dirk H. Rischke

We investigate a linear sigma model with global chiral $U (2)_{R} \times U (2)_{L}$ symmetry. The mesonic degrees of freedom are the standard scalar and pseudoscalar mesons and the v…

The chiral partner of the nucleon in the mirror assignment with global symmetry

Susanna Gallas, Francesco Giacosa, Dirk H. Rischke

We calculate the pion-nucleon scattering lengths $a_{0}^{(\pm)}$ and the mass parameter $m_{0}$ , which describes the nucleon mass in the chiral limit, at tree-level in the framewor…
